write_imageh (3D)

Description

Write color value to location specified by coordinate (x, y, z) in the 3D image object specified by image. Appropriate data format conversion to the specified image format is done before writing the color value. coord.x, coord.y, and coord.z are considered to be unnormalized coordinates and must be in the range 0... image stream width - 1, 0... image stream height - 1 and 0... image stream width - 1.

write_imageh can only be used with image objects created with image_channel_data_type set to one of the pre-defined packed formats or set to CL_SNORM_INT8, CL_UNORM_INT8, CL_SNORM_INT16, CL_UNORM_INT16, or CL_HALF_FLOAT. Appropriate data format conversion will be done to convert channel data from a half floating-point value to actual data format in which the channels are stored.

The behavior of write_imageh for image objects created with image_channel_data_type values not specified in the description above or with (x, y,z) coordinate values that are not in the range (0... image width - 1, 0... image height - 1),0... image depth -1) respectively, is undefined.
